Bi, Hui; Ding, Shusen Orlicz norm inequalities for the composite operator and applications. (English) Zbl 1275.26023 J. Inequal. Appl. 2011, Paper No. 69, 12 p. (2011). Summary: We first prove Orlicz norm inequalities for the composition of the homotopy operator and the projection operator acting on solutions of the nonhomogeneous A-harmonic equation. Then we develop these estimates to \(L^\phi(\mu)\)-averaging domains. Finally, we give some specific examples of Young functions and apply them to the norm inequality for the composite operator.
